PHP:注册表不发送到 mySQL 数据库

Question

我收到的注册表单当前未发送数据或功能未按预期工作。

首页获取了所有必须使用 POST 方法发送到 sign-up.php 的表单，所有用户输入都将被 strip 化，如果用户输入了所有请求表单数据，将被发送到方法 在USER类中注册。 该类处理 mysql 提交。

数据库连接按预期工作。

MySQL日志

MySQL日志仅返回与数据库的初始连接

POST数据的var_dump()

/home/ubuntu/workspace/auth/sign-up.php:5: array(12) { 'email' => string(19) "johndoe@example.com" 'username' => string(7) "johndoe" 'firstname' => string(4) "John" 'lastname' => string(3) "Doe" 'address' => string(15) "Fantasy Road,14" 'cap' => string(6) "010101" 'city' => string(4) "Roma" 'prov' => string(4) "Roma" 'tel' => string(13) "+395551234567" 'passwd' => string(8) "jdoe1234" 'repasswd' => string(8) "jdoe1234" 'submit' => string(10) "Registrati" }

行为 当表单提交到 sign_up.php 时，除了 var_dump() 打印输出之外，我得到了一个空白页。数据库中没有插入任何内容，也没有显示错误

我希望我已经了解了问题所在。

Answer 1

感谢 CodeGodie 的帮助，我发现问题出在位于 sign_up.php 页面的 IF block 中，删除此代码后代码将按预期工作并创建用户。

我将使用 jQuery 来管理它，它也更加用户友好。 谢谢
